Ultrasound imaging systems often struggle to provide high-resolution, three-dimensional (3D) imaging due to limitations in transducer array configurations and sweep patterns. Traditional probes may lack the ability to dynamically adjust imaging coverage or resolution based on clinical needs, leading to suboptimal diagnostic performance. This invention addresses these challenges by introducing an ultrasound probe with multiple one-dimensional transducer arrays capable of generating composite sweep patterns. The probe includes a first and second one-dimensional ultrasound transducer array, each configured to perform individual sweeps. The second composite sweep pattern combines the sweeps from both arrays to form a second composite sweep area, where the arrays collectively generate a second 3D ultrasound data set.

The composite sweep pattern improves spatial resolution and reduces artifacts by leveraging the combined data from multiple arrays, overcoming the limitations of single-array systems. The probe's design enables dynamic adjustment of imaging parameters, making it suitable for various diagnostic scenarios where high-resolution 3D imaging is required.
6. The ultrasound probe according to claim 5 , wherein the second composite sweep area is smaller than the first composite sweep area and the second 3-D ultrasound data set contains less data than the first 3-D ultrasound data set while including the desired 2-D slice location.
This invention relates to ultrasound imaging, specifically to an ultrasound probe that generates 3-D ultrasound data sets with different resolutions. The problem addressed is the need for efficient imaging that balances data volume and resolution, particularly when focusing on a specific 2-D slice within a 3-D volume. The probe includes a transducer array that performs a first composite sweep to capture a large 3-D ultrasound data set covering a broad area. A second composite sweep is then performed, targeting a smaller region that includes a desired 2-D slice location. The second sweep produces a smaller 3-D data set with reduced data volume compared to the first, allowing for faster processing or lower storage requirements while ensuring the critical 2-D slice is included. The probe may adjust sweep parameters, such as beamforming or scan density, to achieve the desired resolution trade-off. This approach optimizes imaging efficiency by prioritizing detailed data only where needed, reducing unnecessary data acquisition in other regions. The invention is useful in medical imaging where real-time performance and targeted imaging are important.

The probe is designed to address limitations in conventional ultrasound imaging systems, particularly those that rely on fixed or interdependent mechanical components, which can restrict imaging flexibility and precision. The ultrasound probe includes a first electromechanical drive and a second electromechanical drive, each capable of independent operation. This allows for separate control of different probe components, such as transducers or scanning mechanisms, enabling more dynamic and precise imaging. The independent operation of the drives enhances the probe's ability to adjust scanning parameters, such as angle, position, or frequency, without mechanical interference between the drives. This improves imaging accuracy and adaptability in medical or industrial applications where real-time adjustments are critical. The probe may also include a housing to support the drives and transducers, ensuring structural integrity while allowing independent movement. The drives can be configured to control different aspects of the probe, such as steering, focusing, or scanning, depending on the application. By eliminating mechanical coupling between the drives, the probe achieves greater flexibility in imaging modes, such as 2D, 3D, or Doppler imaging, without compromising performance. This design is particularly useful in scenarios requiring high-resolution imaging or rapid adjustments, such as cardiac or vascular imaging.

The first sweep pattern is a linear motion along a first axis, while the second sweep pattern is a rotational motion around a second axis. The probe also includes a controller that adjusts the speed and direction of the sweep patterns based on input from a user or an imaging algorithm. The key feature is that both the first and second sweep patterns are adjustable in terms of their extent, meaning the range or amplitude of the linear and rotational movements can be modified. This adjustability allows for precise control over the imaging area, enabling the probe to adapt to different anatomical structures or imaging requirements. The probe may also include sensors to monitor the position and orientation of the transducer array, ensuring accurate tracking of the sweep patterns. The overall system enhances imaging versatility by dynamically adjusting the sweep patterns to optimize image quality and coverage.
